Chosen indicators of meat performance of 98 bulls of Czech Spotted cattle bred in elevation above 720 m above sea-level in the mountain region of Šumava are presented in the article. The fattening was realized in a barn with a deep litter. The feed ration consisted of haylage throughout the year. The bulls were divided into three groups according to their genotype - C100, C75-85R (CxR) and C75-85A (CxA). The highest live weight at slaughter was achieved in the group C100 with 650
kg with the average age of 726 days and the weight of the carcasses of 363.8 kg. On the other hand, the worst results were achieved in the group CxA. For comparison a group of 14 bulls of the Holstein breed was created (H100), which was fattened in
the same conditions. The bulls achieved their highest live weight before slaughter (664.6 kg), but at the highest age (743 days). Statistically significant differences were proven in the meat performance after individual fathers – the best results were
documented with the offspring of the bull BO-837. After the separation of the set of bulls according to live weight at the end of fattening, the highest results were achieved by the group above 700 kg. The best class using the SEUROP method was
achieved by the group with slaughtering live weight between 650 kg and 700 kg.
